All about your K9 Series Subwoofers:
The Rockville K9 series has been our best selling series of subs and it just got even better! Say hello to the K9 V3. This sub is a game changer. We improved the performance and cooling like crazy! Our engineers did some minor tweaks that give major results for bassheads who like to abuse subs! Weather you are an every day user or someone who pushes the limits of your equipment the K9 V3 is for you!
We made the following upgrades that will keep the voice coil cooler improving the subs ability to take constant abuse.
1. The dustcap was upgraded to the same one we use in our Punisher series. It is top of the line. Sure it increased our cost but we kept the low price the same!
2. We added an inner dustcap that stops heat from building up in the voice coil. We also made our pole vent smaller. The combination of these 2 changes keeps the voice coil significantly cooler when you are playing bass heavy songs or test tones.
3. We added a voice coil spacer that vastly improves the performance.
4. The cone has a smooth finish that allows the dustcap to be glued on more securely.

Description:
The dB25 is a 2 channel amplifier with 2,800 watts peak output and 700 watts Dyno Certified power. Here at Rockville we offer the best value in car audio. We therefore want to make it easy for you to compare our products to any brands on the market. The peak rating can be used to compare with brands who use peak ratings such as Boss and Power Acoustik while the Dyno Certified RMS rating can be used to compare with top brands such as Kicker, Rockford, Alpine, etc.
This amp has a fully adjustable 12dB/Octave crossover with differential circuitry. Other features include a subsonic filter, a fully adjustable bass equalizer, and mute and delay soft start technology. The dB25 is protected by a full IC controlled circuit and has professional peak limiter circuitry guaranteeing distortion free music playback at all levels.
The RCA input accepts both balanced and un-balanced inputs. If there is potential inference in the car, the balanced input signal is less susceptible to noise.
The dB amps by Rockville use the top parts and components recommended by Rockville’s very own engineer. These amps are the best sounding out of any series we have ever created. They perform more efficiently resulting in even dB of sound. We created them to be 2 ohm stable just like the world’s most famous amps by Rockford Fosgate, Kicker, etc. If you compare our amp to the most famous amps you will find our amp can compete and, in my opinion, surpass the performance of anything in its class.
Each and every amplifier we manufacture is tested twice. Once at the semi-finished PCB stage of production, and then another test is done at the final assembly. We also run age tests on them. After this is all done, we hire a 3rd party independent company unaffiliated with our factory or with us to go to the factory and inspect 20% of all the production items. We test the power, the controls, and over 20 other tests. We guarantee these amps will satisfy you. We are so confident in your satisfaction of this amplifier that we will offer you a 90 day money back guarantee. If this amp does not perform as well as you expected we will send you a pre-paid shipping label and give you all of your money back. This means if for any reason you want to return the amplifier back for a full refund within 90 days, you can! (Amp must be complete along with the box).
